Overview
System Description
The heated platen kit is a field installed kit to add heat to
the platen. The additional heat may change the viscosity
properties of the material and allow the material to flow
easier through the system.
The heat is controlled by Graco Control Architecture
components: High Power Temperature Control Modules
(HPTCM) and the display module. The display module
provides the user interface for the entire VPM system.
Power Requirements
A 20A (minimum) - 30A (maximum) circuit breaker must
be installed on the incoming power supply.
* Add to power requirements of VPM system. Amps
maximum per leg shown.

Installation
Power Requirements
Ensure that the electrical panel located within the Power Distribution Box has the correct circuit breakers for installing
the kit. If the current Power Distribution Box does not have this configuration, contact your local distributor inquiring
about a Power Distribution Box upgrade kit.
Grounding
Ground the system as instructed within this manual.
Setup
1. Access the Platen
a. Perform Remove Drum Procedure found in
VPM Instructions manuals.
b. Perform Shutdown Procedure found in VPM
Instructions manuals.
c. Thoroughly clean all material that may be found
on the top of the platen.
d. Turn off all sources of power to the machine.
To avoid serious injury or machine damage, all
electrical connections need to be done by a qualified
electrician familiar with local codes.
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.

13.Sensor Resistance Checks
The heated platen system includes a heat sensor and
controller for each of the two optional heated zones. To
check sensor resistance:
1. Make sure the power is off and that the disconnect
switch is in the OFF position.
2. Make electrical resistance checks for the compo-
nents.
3. Replace any parts that have resistance readings
that do not comply with the ranges listed in Table 1.
NOTE: Check resistance at ambient room tempera-
ture (63°– 77°F [17°– 25°C]).
14.Heater Resistance Checks
To check heater resistance:
1. Make sure the power is off and that the disconnect
switch is in the OFF position.
2. Make electrical resistance checks for the compo-
nents. Refer to Table 2. Heater terminal pins are
connected to the HPTCM.
3. Replace any parts whose resistance readings do
not comply with the ranges listed in Table 2.
NOTE: Check resistance at ambient room tempera-
ture (63°– 77°F [17°– 25°C]).
Conduct these electrical checks with the main dis-
connect OFF.

Clean
Keep heat sink fins clean at all times. Wipe the fins
clean with a dry cloth or clean them using compressed
air.
NOTE:
Do not use conductive cleaning solvents on the tem-
perature control modules.
Install Upgrade Token
NOTE: The Motor Control Module, Fluid Control Mod-
ule, and Temperature Control Module connection to the
system is temporarily disabled during the installation of
upgrade tokens.
To install software upgrades:
1. Use correct software token stated in the table. See
Graco Control Architecture™Module Programming
manual for instructions.
NOTE: Upgrade all modules in the system to the
software version on the token, even if you are
replacing only one or two modules. Different soft-
ware versions may not be compatible.
All data in the module (System Settings, USB Logs,
Recipes, Maintenance Counters) may be reset to
factory default settings. Download all settings and
user preferences to a USB before the upgrade, for
ease of restoring them following the upgrade.
See manuals for locations of specific GCA compo-
nents.

Platen Maintenance
If the platen does not come out of the pail easily when
the pump is being raised, the air assist tube or check
valve may be plugged. A plugged valve prevents air
from reaching the underside of the plate to assist in rais-
ing it from the pail.
1. Turn off main disconnect.
2. Relieve pressure and disassemble air assist valve.
Refer to Supply Systems Repair-Parts manual.
3. Clear air assist tube in platen. Clean all parts of
valve and reassemble. Refer to Supply Systems
Repair-Parts manual.
4. Remove bleed stick from platen. Push bleed stick
through bleed relieve port (T) to remove material
residue. See FIG. 7.
5. Remove platen covers. See FIG. 7.
a. Remove platen cover fasteners (70).
b. Remove both platen covers (49) and ground
wire from platen.
6. Remove any excess fluid. Use a soft wire brush on
heater coils (48). See FIG. 7.
7. Inspect platen heater blocks (43) or heater (48) for
burn or melt spots. Replace platen heater if neces-
sary. See FIG. 7.
8. Check for loose connections and damaged wires.
9. Follow steps in reverse order to reassemble platen.
NOTE: Torque platen cover fasteners (70) to 60 +/-
10 in-lbs (6.8 +/- 1.1 N•m) for 55 gallon platen.

Troubleshooting
Before performing any troubleshooting procedure:
1. Perform Pressure Relief Procedure found in vpm
Instructions manuals.
2. Turn main power OFF.
3. Allow equipment to cool.
Try the recommended solutions in the order given for
each problem, to avoid unnecessary repairs. Also,
determine that all circuit breakers, switches, and con-
trols are properly set and wiring is correct before assum-
ing there is a problem.
Common Problems
Problem Cause Verification Solution
Heating is slow. Heater defective. Measure resistance of
heater.
Follow Heater Resistance
Checks, page 14.
Low power. Measure voltage across cir-
cuit breakers. Voltage
should measure between
190 and 275 Vac.
1. If voltage is lower than
expected, use electrical
schematic to locate
faulty wiring or connec-
tion.
2. Have a qualified electri-
cian service electrical
components.
Heating over shoots. Shorted module. Verify for given zone that
temperature does not
increase when zone is dis-
abled.
Verify RTD wire or heater
power cord is attached to
correct heat module.
Replace module.
